ZEtUY i. G-ILIBUIRG, 0F KALAMAZOO,MICHI%ANE FILING-MAUHINE Specification of Letters Patent. Pfljtfllltea B 3 11 191*? Application filed January 24, 191?. Serial No. 144C281;

To all whom it may concern: a

Be it known that 1, Her 0. (impose, a citizen ot the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful improvements in Filing-Machines, of which the-following is a specification.

'lhis invention relates to improvements in tiling machines.

My improved tiling machine is especially designed by me as an attachment to a drill press or other machine tool, and the embodiment illustrated herein is adapted for that purposev 'lhe main objects of this invention are:

First, to provide an improved filing machine.

tlecond, to provide an improved filing machine adapted as an attachment for machine tools.

Third, to provide an improved filing ma chine which is comparatively simple and economical in structure and is at the same time ellicient in use.

l urther objects, and objects relating to structural details, will definitely appear ltrom the detailed description to follow.

it accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims, a

it structure which is a preterred embodiment of my invention is clearly illustrated in the accompanying drawing. forming a part of this specification, in which:

Figure l is a perspective view of my improved tiling machine, a portion of the work table being broken away to better illustrate the parts, the driving spindle being shown in one position by dotted lines.

Fig. H is a vertical longitudinal section on line corresponding to line 2-2 of Fig. I.

llll is an enlarged detail section through the supports for the adjustable table, on a line corresponding to line 3-? ct ll,

ll? is a detail section on a line corre sponding to line 4-4 of Fig, I through the tile holder chuclr.

l ig. V is an enlarged detail section on a line corresponding to line 5-5 of Figs. I and llll, showing details of the connections to the file holder la the drawing similar reference char acters rclier to similar parts throughout the several views, and the sectional views are taken looking n the direction ofthe little arrows at the ends ot' the section lines.

Referring to the drawing, 1 provide a frame designated generally by the numeral 1, having a base 2 adapted to be mounted on the bed oi a drill press or other machine tool in position to be driven by the spindle of suchmachine. The work table 3 is provided with a pair of spaced arms l l slotted longitudinally at. 5 to receive the supporting bolt 6. T his bolt is provided with a winged nut 7 by means oi which the bolt may be clamped up to support the table in its adjusted positions, it being adjustable vertically and also being capable of tilting adjustment. j j

The frame is provided with an opening 8 atone end providing in effect an upright 9. A way is provided tor the reciprocating file holder 10, theway comprising a channellikeportion 11 formed in the upright'E) and a face plate 12secured thereto by screws 13.

The rear wall of this way is longitudinally slotted at l-l to receive the pitman pin 15. A driving shaft 16 is journaled in theframe and provided at its inner end with the crank 17, which has a counterbalance 18. The pitman l91is connected to the cank by the wrist pin 20. At its outer end the shaft 16 is provided with a beveled gear 21 meshing with a beveledgear on the driving spindle E23. -lhis drivingspindle is adapted to be received by the chuck or a drill press or other machine tool, j I

To adapt the machine to different types of machine tools the spindle 23 is mounted in an adjustable support 24. This support is pivoted upon the shaft 16 and detachably secured to the frame by the bolt 25. The lower end of the support is slotted at 26 and adjusted to the shaft by means of the screw 27. The support is not clamped upon the shaft but is adjusted thereto to provide a suitable bearing fit.

The file 28 is secured in the tool holder, which is provided with a suitable chuck to receive the same, by means of the set screw 29, Any suitable term oi? chuck may be employed in this relation,

With the parts arranged as l have illus trated and described, the machine may be readily adjusted to a drill press or other machine tool without any disorganization or reorganization of such machine, and as it may be r uiclrly attached or detached it does 'detachably secured modifications and embodiments which I contemplate and which are included-in the scope of the following claims, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as conditions may require.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a structure of the class described, the combination of a frame, a work table mounted on said frame for adjustment, a file holder, a slide Way in which said file holder is mounted to reciprocate below said table, said table having an opening through which a file arranged in said holder projects, a driving shaft journaled in said frame, a counterbalanced crank on the inner end of said shaft, a pitman connecting said crank to said file holder, a driving spindle, a supporting bracket for said driving spindle pivotally mounted on said shaft and to said frame, and meshing beveled gears on said spindle and shaft.

'2. In a structure of the class described, the combination of a frame, a work table mounted on said frame for adjustment, a file holder, a slide way in which said file holder ismounted to reciprocate below said table, said table having an opening through which a file arranged in said holder projects, a driving shaft journaled in said frame, a counterbalanced crank on the inner end of said shaft, a pitman connecting said crank to said file holder,a driving spindle tiopies of thispatent may be obtained for five cents each,

geared to said driving shaft, and an adjustable support therefor pivotally mounted to rotate about an axis concentric with the axis of said driving shaft.

file holder, a slide way in which said file holder is mounted to reciprocate below said table, said table having an opening through which a file arranged in said holder projects, a driving shaft journaled in said frame, a counterbalanced crank on the inner end of said shaft, a pitman connecting said crank to said file holder and a driving spindle geared to said driving shaft, and adjustable about the axis thereof.

l. In a structure of the class described, the combination of a frame, a reciprocating file holder, a driving shaft journaled in said frame, a crank on the inner end of said shaft, a pitman connecting said crank to said tile holder, a driving spindle, a supporting bracket for said driving spindle pivotally mounted on said shaft and detachablv secured to said frame, and meshing beveled gears on said spindle and shaft.

5. In a structure of the class described, the combination of a frame, a reciprocating file holder, a driving shaft journalea'l in said frame, a crank on the inner end of said shaft, a pitman connecting said crank to said file holder, a driving spindle geared to said shaft, and a support for said driving spindle, adjustable about the axis thereof.

In witness whereof, l. have hereunto set my hand and seal in the presence of two wit nesses.
